Oil residue in the air and on kitchen surfaces can harbor the odor long after the dishes are done. Breaking down the oil smells promptly combined with good ventilation can get rid of the aroma of cooking oil, along with any other unfavorable cooking smells.
A soapy sponge cuts through the oil on walls and counters, just like it does on your dishes. Wipe down countertops, the stove and walls to remove any grease residue. Don't forget to wash the dishes – an oil-coated pan can infuse the whole room or house with the fragrance of cooking oil. Run the kitchen ventilation fan and open windows to move the oil out of the air.
For lingering odors, set a bowl filled with vinegar, baking soda or fresh coffee grounds in the kitchen overnight. These materials absorb odors from the air, but you may need to replace them for a second day for especially strong odors. Simmering cinnamon sticks, apple peels or orange peels in water can help mask the odor if you need a quick fix. Alternatively, mix 2 tablespoons vinegar with a cup of water and boil it for 3 to 5 minutes. The vinegar absorbs the oil smell so it dissipates more quickly.
